10 is what percent of 840000 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 840000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 840000, so we can write it down as 100%=840000.
4. We know, that x% equals 10 of the output value, so we can write it down as x%=10.
5. Now we have two simple equations:
1) 100%=840000
2) x%=10
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=840000/10
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10 is what percent of 840000

100%/x%=840000/10
(100/x)*x=(840000/10)*x       - we multiply both sides of the equation by x
100=84000*x       - we divide both sides of the equation by (84000) to get x
100/84000=x
0.0011904761904762=x
x=0.0011904761904762

now we have:
10 is 0.0011904761904762% of 840000
